Description

Wärmeisolierungsmaterial Den Gegenstand der Erfindung bildet ein Wärmeisolierungsmaterial, insbesondere für Rohrpackungen oder Rohrverkleidungen, das aus einer Masse von getrennten und unverfilzten Mineralfasern, z. B. Asbest, besteht.Thermal insulation material The object of the invention is a thermal insulation material, especially for pipe packings or pipe cladding consisting of a mass of separate and unfelted mineral fibers, e.g. B. asbestos.

Es ist bereits bekannt, Asbestplatten mit flüssigem Paraffin zu tränken, oder man hat Asbest mit Zinkoxyd behandelt und die Masse mit Chlorzink und palmitinsaurer Tonerde getränkt. Es handelt sich hier stets um die Behandlung von Platten. Die Behandlung des Asbestes mit Zinkoxyd macht ihn nicht wasserabstoßend, da Zinkoxyd Feuchtigkeit anzieht.It is already known to soak asbestos sheets with liquid paraffin, or asbestos has been treated with zinc oxide and the mass with zinc chloride and palmitic acid Soaked in clay. It is always about the treatment of plates. the Treatment of the asbestos with zinc oxide does not make it water-repellent because zinc oxide Attracts moisture.

Es wurde ferner vorgeschlagen, Asbest als Faser, Gewebe oder Platte mit Aluminiumsalzen zu behandeln, um dem Erzeugnis eine größere Härte und Widerstandskraft gegen äußere Beschädigung zu verleihen. Dagegen haben die Aluminiumsalze nicht die Eigenschaft, den Asbest wasserabstoßend zu machen.It has also been suggested to use asbestos as fiber, fabric or sheet To be treated with aluminum salts to make the product harder and more resistant to lend against external damage. In contrast, the aluminum salts do not have that Property of making the asbestos water-repellent.

Erfindungsgemäß sind die einzelnen Fasern durch Behandlung mit wasserabstoßenden Stoffen, wie wasserunlöslichen Metallseifen, Harz- oder Kautschuklösungen, wasserabstoßend gemacht, wodurch das Bestreben zur Kapillarität zerstört wird und das Fasergut seine lockere Form behält. So können z. B. Zinkstearat oder Aluminiumstearat oder -resinat zur Behandlung .des Fasergutes, wie gerissenen Asbestes o. dgl., dienen. Die Metallseifen können entweder in trockener Pulverform oder als Lösung oder Suspension verwendet werden.According to the invention, the individual fibers are treated with water-repellent Substances such as water-insoluble metal soaps, resin or rubber solutions, water-repellent made, whereby the tendency to capillarity is destroyed and the fiber material its maintains a loose shape. So z. B. zinc stearate or aluminum stearate or resinate for the treatment of the fiber material, such as cracked asbestos or the like., are used. The metal soaps can either be used in dry powder form or as a solution or suspension will.

Die Verwendung des Materials nach .der Erfindung mit der wasserabstoßend gemachten Mineralfaser hat den Vorteil, daß es einen besseren Wärmeschutz bei Rohren gibt, bei denen die Wärmeschutzmassen, wie z. B. bei Dampfleitungsrohren, durch undichte Stellen feucht werden können und dann besser die Wärme leiten. Zur Vermeidung des Feuchtwer.dens der Mineralfasern hat man bisher weit umständlichere Mittel vorgeschlagen. Da durch die erfindungsgemäße Behandlung das Material seinen losen und flockigen Zustand behält, kann es leicht und gleichmäßig in unregelmäßige Räume gepackt werden und besitzt höchste Wärmeisolierkraft.The use of the material according to the invention with the water-repellent Made mineral fiber has the advantage that there is better thermal protection for pipes there, in which the heat protection masses, such. B. in steam pipes through leaks can become damp and then conduct the heat better. To avoid of Feuchtwer.dens mineral fibers, far more complicated means have been proposed up to now. Because the treatment according to the invention makes the material loose and flaky Keeping state, it can be packed into irregular spaces easily and evenly and has the highest thermal insulation power.

Vorteilhaft wird der zerkleinerte bzw. gerissene faserige Mineralstoff mit zerkleinertem Schwamm, der vorzugsweise von Verunreinigungen, wie Salzen, befreit ist, innig vermischt.The shredded or torn fibrous mineral material is advantageous with a crushed sponge, which preferably removes impurities such as salts is intimately mixed.
